I ELECTRIC SEALING DEVICE.

Application filed February 15, 1921, Serial no. 445,248. Renewed January 2, 1923.

To all whom it may concern: 7 i

Be it known that I, WALTER Ransom-a citizen of the United States, and a resident of the city and State of New York, have invented certain new and useful Improvements in Electric Sealing Devices, of which the following is a specification. I

My invention relates to a mechanism. for applying sealing wax or a similar substance toenvelopes, packages and the like and for impressing on said substances,.while still in a plastic state a seal by means of av suitable die. The object of this device is to provide a hand operated mechanism of simpleconstruction, electrically heated to bring the sealing wax into a plastic condition and a seal carrying medium also mechanically operated which shall be sufficiently cooled by the presence of a cooling medium such as ice or cold water so as toavoid adhesion of the sealing wax tothe seal when the seal impression is being made. In the accompanying drawings, forming part' of this specification, I have illustrated a preferred embodiment of my present invention. Fig. 1 is a front elevation of the electric sealing device, and Fig. 2 is a side elevation with parts broken away.

My improved seal press comprises a main metallic frame Awith a base 3 which may be perforated. as at 4, two standards 5 and 6 connected by a transverse top member 7, and a handle 11 mounted thereon. This handle is provided with a tubular internal recess 11 to receive, for sliding engagement the upper end of a guide rod or, piston 9, about which a coiled spring 10 is provided to exert upward tension against the handle 11. The recess 11 is of suficient depth to permit of vertical movement of the handle relative to the guide rod 9 to permit of the depression of the spring 10. The pair of standards 5 and 6 on their inner sides also support a sliding frame B, comprising two arms 13 and 14: and a transverse top member 15, the arms 13. and 14- being parallel with one another andparallel with the standa r ds 5 and 6. These carriers are provided to support a swinging cup 16 by means of a pivoted frame 17 which "comprises two vertical oppositely located members 18 and 19 and a transverse cross member 20 upon which the cup is secured as by a screw 21.

' To effect the swinging movement of the frame 17 and its cup 16 I provide arms 18 and19 of the frame 17 each with apin 22 and a pin 28secured on each of the arms 13 and 14 and projecting through holes in arms 18' and 19. These pins when thecup is in its lowerlposition are substantially superposed and slide in the vertical portion of a slot 24 provided in each of the vertical standards 5 pins 22 and 23 will be. located in the vertical portion of the slot 24, whilewhen the cup and its arms are in inoperative or raised position the pivot pin (or lower pin) 23 will have been moved, as hereinafter described,

upwardly in the vertical slotfl24c and the upper pin ,22 will have entered into. the curved portion. 25-of the slot 24, the, tilting or swinging of the cup being effected bysuch slot curvature.

Between the pair of standards 5v and ,6

sealing wax receptacle or. cup 26' is fixedly secured to such standards, at either side, by means such as a screw 27 This, cup 26 may be made cone shaped, of copper orany other desired metal and has at its lower end an outlet 28 having a plug or valve 29 vfrom which a rod 30 extends upwardly through the interior of the cup for the'purpose o v opening. orclosing said Outletby means of a spring-pressed operating lever v51 .pivotally mounted on the top of frame A, said lever having handle 32 to which the-rod 30 is connected. The handle or .knob 11 surmounting the mechanism above described carries a pair of laterally arrangedrods"33 extendingdownwardly and passing through perforations inthe transverse top member 7 of theframe A, and the lever 31. These rods 33 are securedflto the transverse top memher of the inner sliding frameB in any desired manner; j M

1 Having reference tothe sealingwax cup 26 it will benoted thatthe wallof-the receptacle preferably contains an electric heating element ofany ap'proved construction, a

to which current is supplied by means of wire s.34:, extending through suitableholes 35 and any connector plug of well'known' character. It will be noted'also' that the swinging cup 16 provided with acap '37 having an inlet 0138111115 238 and a screw'39 for closing the same. At the outer side of the bottomof this cup the desired seal is secured as by soldering the same thereto, although the same may be applied in any other desired manner, as by screwing the same thereon.

I shall now describe the operation of my construction The inner frame B and the arms and handle 11 connected thereto are maintained in inactive or upper position as shown in full lines under the tension of the spring 10. In this upper position the pin 22 is maintained in the curved port-ion 25 of the slot 24- while the lower pin 23 is maintained in the vertical portion of said slot. In this position the swinging cup 16 is in tilted position and out of the pathof the outlet 28 of the wax cup 26. In order to supply the requisite amount of sealing wax (which previously has been heated in the cup by the electrical heating element) the handle 32 is depressed thus raising through the spring pressed lever 31 the outlet valve rod 30 and raising the plug or valve 29', whereupon the wax will drop upon the article to be sealed. When pressure on the knob 32 is released the plug will again become seated for closed position. Thereupon the handle 11 and its appurtenant parts are depressed whereby the pivoted swinging frame 17 is brought vertically above the wax deposited and directly beneath the wax cup 26. It will be understood that in this position the pins at 22 and 23 are both in the vertical portion of the slot 24. The continued downward pressure will carry the die or seal 37 forming the bottom of the cup 16 into pressing contact with the wax deposited which is in a more or less viscuous or plastic state. Upon release of pressure on the handle 11 the cup will again assume its inoperative or tilted position. The presence in the cup 16 of either ice or cold water prevents the seal 37 from becoming unduly heated whereby the adhesion of the sealing wax thereto is completely avoided. It has been found that several hundred impressions could be made without this adhesion and that although the seal or die had been repeatedly carried into contact with the heated wax the water in the cup remained relatively cool, at least sufficiently so to overcome the objectionable adhesion of the wax to the seal.

I claim:

1. A device of the character described, comprising a frame, a receptacle rigidly secured to said frame and having an outlet, a valve for normally closingsaidoutlet, a receptacle adapted to contain a cooling medium carrying a die, said receptacle and die beingrmovably supported on said frame, means for opening saidoutlet, and means for moving said. die to a position in which ,ese

it will make an impression on material pre viously delivered from said outlet.
